What a silly idea, that a free market would be better and more efficient delivering mail than the government which loses billions a year? Fedex delivers anywhere you want - I'm sure they would love to deliver mail too with their network as would UPS etc. and you know how reliable they are as opposed to USPS.
Free market won't deliver to unprofitable zip codes, won't treat unprofitable diseases and cannot effectively account for negative or positive externalities created by a given business.
